CSS JIT: support :scope
https://bugs.webkit.org/show_bug.cgi?id=135733

Reviewed by Benjamin Poulain.

Implement :scope for CSS JIT. It introduces scope field to CheckingContext
and it makes CheckingContext more similar to SelectorChecker::SelectorCheckingContext.
And since :scope requires CheckingContext, QueryingRules can accept SelectorCheckerWithCheckingContext.

Merging platforms mixes baselines and targets into reported data
https://bugs.webkit.org/show_bug.cgi?id=135260

Reviewed by Andreas Kling.

When merging two platforms, move test configurations of a different type (baseline, target)
as well as of different metric (Time, Runs).

Also avoid fetching the entire table of runs just to see if there are no remaining runs.
It's sufficient to detect one such test_runs object.

Web Inspector: DebuggerManager commands should return promises
https://bugs.webkit.org/show_bug.cgi?id=135690

Reviewed by Timothy Hatcher.

Convert the existing debugger commands to return promises. This
requires separately waiting for protocol command's promise to be
fulfilled, as well as waiting for the appropriate DebuggerManager
event. If the protocol command promise is rejected, tear down the
single-fire event listener.
